Half-Life 2 Walkthrough & Strategy Guide

Swim down the canal until you reach a large red object with a ladder on
the left side. Climb up the object and drop down into the opening on
top. Two members of the resistance are inside where your suit will be
recharged. Notice the G-man on the television screen. Leave the trailer
and smash through the boards in your way. Around the next pile of
garbage is the first encounter with a barnacle. These balls of goo
stick to the ceiling and drop down a sticky line. This line attaches to
anything that touches it and drags it up to the mouth of the barnacle.
These enemies can be killed with about six or seven pistol shots. An
easier way to get by them is to throw some garbage into the line and
let them munch on that, instead of your skull.

At the end of this tunnel there are some resistance fighters being shot
down. The best route is to make a right into the open area and hug the
wall. Enter the pipe that the resistance fighter beckoned you from
before he was shot. Kill the two officers ahead and walk down the pipe
into a small room that contains a

Go up the ladder straight ahead. At the top there are two officers; one
of them is manning a gun turret. Sneak to the left and blow up the red
barrel behind them to take them out. Then use the action button to man
the turret. A slew of officers will appear in front of you and to the
side. Shoot the barrels on top of the bridge and on the street to take
them out. Also, be sure to shoot the wooden platform on the right so
that if falls and creates a path down the canal. After all of officers
are taken down, get away from the turret to avoid some missiles will be
fired at you from an APC. Run down the right side of the canal into
another tunnel.

At the end of the tunnel take a left and a resistance fighter will
lead you down the next section of the canal. At the end of this tube,
stick to the left wall and jump up to the next pathway which leads to a
square room filled with water. This appears to be a dead end. Jump
into the water and smash the crates for healing items, then Combine
officers will drop exploding barrels into the water from above. Dive
under the water to avoid damage and the barrels will blow open the
previously barred path. Swim towards the opening and you will climb
into the next tube.

At end of the next tube there will be two officers that hop down into
the canal. Take them out, and walk ahead. There is a rickety wooden
bridge ahead, that will soon be overrun with officers. Shoot the
barrels at the base of the bridge to bring the whole structure down,
taking the Combine with it. After the bridge an officer will come from
the
right and the left, so be ready for them. Then climb the mound of dirt
and move the barrel blocking the small entrance to the next area.

The next tunnel is filled with slick mud and barnacles. Be sure to grab
barrels and toss them at the barnacles ahead. Around the corner, there
are some red barrel, light one on fire and roll it down the pathway at
the large group of barnacles ahead. The explosion will cause the lot of
them to retreat to the ceiling. Around the corner there is a dead body
and some health.

Jump across the wooden platforms in a horseshoe pattern and enter the
next pipe. In this dark room there is a wooden plank positioned on top
of a concrete tube. Pick up the cinder blocks and place them on the
high side of the plank to act as a counter balance. Then use the wood
as a ramp to the next area.

This open area curves around to the left. As you slide down into the
lower area, quickly jump up to the left to reach a ledge as a
helicopter fires at you. Walk across the wooden planks to the blue
door. Pick up the barrels that block the door to gain access to an
alley. Take cover under the roof. There is a barnacle on the left ledge
which blocks some health.

Behind the blue door there is a skinny hall. Look down to see a Lambda.
Take a right down the ladder to obtain health packs and some ammo. Take
a left and then a right into the tunnels. Here there are some exploding
barrels that should be lit and thrown down the slippery ramp where
there are barnacles waiting at the bottom. Zig-zag back up the ramp and
do the same thing at the next slipper ramp with another red barrel.
After this section there is a door leading outside. Take a left and run
down the hall into the hall on the left before the helicopter fires on
you again. You will see a resistance poster on the wall as you walk
down the next hall.

Hack your way through the crates to a resistance fighter's hide out. He
warns you that manhacks will soon be attacking, which they do as he
talks so you. Smack these slicing bots down with your crow bar. There
are supplies on the platforms in this area, so stack crates to get to
them. Down the next two halls, there are two more groups of three
manhacks. After the second group, go down the hall to the second arched
entrance to find some ammo and health in a small room. Then walk
outside and bash through the crates to another door. Turn around to
intercept the swarm of manhacks that come in behind you.

Drop down to the tunnels and some officers will appear ahead of you.
The officer that comes down from the rope is holding an SMG. Shoot the
barrels to cause explosions. In the area where the officer dropped from
the ceiling, turn around and crawl into the vent on the ground to find
some health and ammo. Be prepared for a zombie that appears at the end
of the tunnel. When you turn around to exit the tunnel, another officer
will drop from the ceiling.

Walk down the hall and turn the corner to find an area filled with
water and a spinning set of fences under the surface. There is an under
water tunnel on the bottom of the left side. Don't go under until you
are on the far side and the spinning fence makes it accessible. Then,
swim through the tunnel until you reach an opening where you can pop up
and grab some air. Continue ahead and there is a large pipe leading
outside.

In the stairway to the left, watch out for the barnacle and the two
officers that appear at the opening of the tunnel. In front of the
barnacle there is a box containing health and ammo. At the opening
there will be two more officers as well as a manhack. Go outside to
climb on top of the red pipe and then double back over the steaming
vents. Wait for breaks in the steam bursts before you cross. Then jump
to the right, to avoid the barnacles. There are some barrels here that
can be used to distract them as you jump by. There is also health and
ammo on the ledge in between the steam bursts.

Crawl through the shaft until you drop into a room filled with red
barrels. Destroy the manhacks that flood the room, but be careful if
you decide to go with a pistol, the resulting explosions can be deadly.
In the corner of the room you can climb up a stone incline to reach
some health. Climb the ladder in the center of the room to reach a
silver pipe that leads to the second level. You now enter a vertical
room with a long ladder and a large number of pipes. At the bottom of
the ladder is a supply crate containing full health. The goal of this
area is to reach the valve on the red pipe that raises the water level.
Climb to the top of the ladder and drop down onto the white pipes to
get there.

As the water rises, return to the room filled with exploding barrels
and go down to the bottom level using the hole where the ladder is
located. Jump into the water to avoid the manhacks. Swim through the
red-lit pipe on the bottom level to reach a small room with a ladder.
In order to cross the gap, you will need to swim to the bottom of the
room and break the wooden planks with your crowbar. This will release
some large wooden spools that act as a bridge to the other side.

Once you exit this room you will drop into a narrow tunnel. Officers
will approach from one side and a manhack will come from the other.
Walk towards the manhack and take it out, then deal with the officers.
A flow of manhacks will continue to appear as you jump up onto the
ledge where the officers were standing. Grab the contents of the supply
crate and enter the dark hallway. There's a door to the left and a dark
room ahead. Beware of the barnacle in the dark room and grab the health
and ammo.

In the lit entrance, climb up the ladder and grab the supplies at the
top. Notice the lambda on the wall. Make your way across the planks and
avoid falling down to find another lambda and some ammo. Drop down and
walk out of the tunnel into an open area. The crackle emanating from
your suit indicates that nearby water is radioactive and will inflict
damage. Jump onto the rusty pipes and walk to the left to find another
supply dump. Then drop down and meet a citizen who has an infinite
stock of SMG ammo as well as some health and power cells.

As you leave the supply area, some citizens ahead will be killed by
shells containing head crabs. These creatures will burrow into the
ground and then pop up when you approach. Advance slowly and prepare to
blast them when they appear. A man is attacked by one of the creatures
behind a fence; put him out of his misery. Up ahead there are two
zombies who are controlled by the crabs. Do not let them get near you,
and watch out for the barrels they hurl. As you navigate the area, stay
away from electricity and the metal surfaces surrounding it. Also, stay
away from the radioactive water. After the dangling power line, a
zombie will attack from the left. There is also a supply crate in the
corner. Walk through the storage car without touching the walls, and
smash the crates on the floor. Be prepared for a shell to land at the
exit and take care of the crabs that come out of it. Just because you
have a pistol, don't forget how powerful the crowbar can be against
crabs and manhacks.

After the storage car, you will encounter another zombie that rises
from the muck, and another shell will drop from the sky. Use the
flaming barrel to your advantage against these creatures. Then, walk on
the wooden planks across the water to find the airboat. Hop into the
boat and take off across the pond until you reach a dead end. You will
need to exit the boat at the concrete block and open the gate ahead of
you. Look out for headcrabs while doing this, and grab the supply crate
next to the crank.
